Application'filed September 1S, 1514. Serial No, 862,092.

To all whom it may concern:

Be it known that I,'HERMANN Honneonn, a citizen of the Republic of Switzerland, residing at \Vetzikon, Switzerland, have invented new and useful Improvements in Spinning and Twisting Spindle"Bearings;'

and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and;

use the same, reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of this specification.

In spinning and twisting spindle bearings it is known to have the. whorl, integrally connected with the spindle, and rotatable on balls 'on the outer portion of the fixed bear- I ing-box. In this kind of constructions the construction whiclil unites the two above mentioned cl'i-aracteristics, thus annulling the single disadvantage of both known constructions with the result that with but little requirement of power and lubricant, a high speed, without oscillations-is attained.

n the accompanying drawings is shown b way of example one formof the present invention.

.Figure 1 is a vertical section and Fig. 2 is a cross section (line -AB of Fig. 1). Fig. 3 shows a modified form of the depending portion of the spindle, the depending. portion having a screw-groove. Fig. 4 shows a modification of the main support.

" In the drawings lindicates the externally threaded lower hollow shaped portion of the main support which extends through the opening in the rail. orpart of the frame of a Specification of Letters Patent.

4 is the hollow bearing bolster, resting within the lower portion of the main supp ort.

A spring 7 is placed in a recess groove 5 on the outer portionof the bearing bolster and engages 1n a recess orgroove' 6 of the lower portion 1 of the main support. The outer diameter of the hollow bearing bolster a is somewhat smaller than the correspond-J ing bore of the lower portion of the main support, so that the spindle may adjust itself into the axis of the center of gravity. The bearing bolster rests upon a shoulder a in the inside of'the hollow shaped lower portion of the main support.

The oil chamber 3 communicates by a groove 8 and a hole 9 with the oil' cup 10 the oil being filledtherein to the level 11. The bearing bolster 4. carries the spindle l2, and

the whorl 13 which is fixed thereon, and dips with its lower extremity 13 into the oil cup 10. Thewhorl is held by a hook 14 in a' known manner. The spindle 12 and the whorl 13, 13 are mounted rotatably' by means of the ball or roller bearings 15,16

on the outer portion of the bearing bolster 4..

Instead-of ball bearings or roller bearings, combined ball and roller-bearings could be provided. For taking up the axial pressurea thrust bearing could beprovided. The spindle 12 has a depending portion or prolongation 12 depending in the bore 4:" of the hollow bearing bolster, the diameter of which is larger than the diameter of the prolongation portion '12, of the spindle so that no friction within the'bearing bolster takes place. The depending portion or prolongation 12' and the bore i are straight or tap'ered toward the lower end. In consequence thereof by rotation of the spindle 12 the oil will be caused to rotate and to raise higher than the level-11 to the bearing 15. Fig. 3 shows a depending portion or prolongation 17 provided with .a screw-groove 18. H From the bearing 15 the oil will flow to the lower.
